Nice blocks that I use to weight miniature projects while glue dries. Price is better than local stores.

The blocks I recieved were NOT a matched pair. The squareness and parallelism in the description may be true but the set I got had 2 thou variation between the two blocks on any given side. (Thats 0.002 variation) and seeing how I have trammed my mill within 4 tenths (thats under 0.0004) across 15", this set is worthless to me. Maybe when I get a surface grinder, I'll fix them but I went ahead and bought a MATCHED set from another company for about twice as much as these cost.I do NOT recommend these to be used as a pair to project a surface.

Everything came in a nicely seal box and was exactly what I was expecting. Arrived 2 days early too.

These are very accurate and extremely square. My only complaint was that they came packed in Cosmoline grease. I ended up soaking and periodically scrubbing them in 99% isopropyl for 3 days to remove the Cosmoline but they are great now and that horrible smell is gone.
